It's just all kinds of suckiness when people that you should be able to reach out to for help and they just don't get it nor want too. At times like this , your best thing to do is accept the fact that they cant be who "you would like them to be" . It's really up to you if you want to have a relationship with them in general.
.

Find support in other people that are understanding, here on PC , Keep a crisis phone # in your cell phone, My Pdoc and T are part of a mental health care company, they have what is called a "Warm line " just someone to call and talk to for how every long it takes to calm me down ,Maybe check into your area and see if there is something like that.

Stay safe
